1. An implantable cardiac vein lead adapted to be advanced through twists and turns of a cardiac vein and branch vessel openings to locate at least one electrode at an implantation site comprising:

  • an elongated lead body extending between a lead body proximal end and a lead body distal end and having a lead body axis, the lead body further enclosing at least one electrical conductor extending between a proximal lead connector element of the lead body and a distal electrode of the lead body adapted to be implanted in contact with a cardiac vein at an implantation site; and

    an elongated flexible distal guidewire extension affixed to and extending from the lead body distal end to a distal guidewire extension distal tip and having a pre-formed bend formed along the length of the distal guidewire extension that disposes the distal guidewire extension distal tip lead laterally away from the lead body axis to enable aiming of the distal guidewire extension through twists and turns of a cardiac vein and branch vessel openings.
